WIREY-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 350,982, dated Qctober 19, 1886.

Application filed March 29, 1886.

To all whom it may concern.-

Be it known that I, OLE O. KITTLESON, a citizen of the United States, residing at Rock Falls, in the county of Vhiteside and State of Illinois, have invented certain new and useful Improvements in \Vire-Barbing Machines; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled o in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

seating barbs on fence-wires, and has more special reference to certain mechanism for coiling the barb.

My machine is intended to operate upon fence-cables consisting of at least two wires or strands, whichstrands are bent across each other at intervals before being twisted, as shown in Figure 3; and my invention consists of the mechanism, hereinafter described, for coiling the central portion of the barb between such strands and around the point wheresuch strands cross each other, as shown in said Fig. 3.

In the upper barb of Fig. 3 the upper point,

0c, of such barb was originally projected between the parallel strands g directly under andin the same direction in which said point at now extends. It was then seized by the coiler, and while certain mechanismbent the strands g g past each other in a vertical plane contiguous to the side of such barb, the coiler caused such point x to perform a complete circle, in a substantially horizontal plane,around the point of mutual crossing of the strands yy.

This operation produced a circle at the center of the barb, and left the point x projecting in its original direction and with each of the strands y above the barb at one side of the coil and below the barb at the other side of such coil, as shown in Fig. 3. The barb was then cut from the main wire at the point it, andthe barb was then complete and the strands ready to be twisted in the usual mode.

The mechanism which accomplishes the 5 above described seating of the barb I claim as My invention has reference to machines for Serial No. 197,074. (No model.)

my invention, and I will now proceed to describe the same.

Fig. 1 is a plan view of a machine enibodying my invention. Fig. 2 is a Vertical longitudinal section at the side of the strands 5 y y in Fig. 1. Fig. 3 exhibits twoviews ofthe barb when seated. Fig. 4 is a side elevation of the mechanism involved in rotating the coiler G in a horizontal plane and the devices employed to interinittingly elevate and depress such coiler.

The mechanism shown in Fig. 4 is placed transversely of the machine about opposite the entrance of the barb H.

A is the bed of the machine, on which is transversely jonrnaled the rotating shaft B, driven by the pulley B, or in any other suitable way. The strands y y are intermittingly fed in the usual mode, by means of a pitinan,

B attached at its inner end to a cranlcwrist, B on the shaft 13, and at its outer end to a loose collar, B carryinga pawl, B, which latter intermittingly engages a ratchet, B fixed on the shaft 0, which latter carries the feedpulley O. A short shaft (not shown) is seated 7:, on the boxes 0, directly above and parallel with the shaft 0, and carries a pulley corresponding to the pulley 0, directly over the latter, such supposed shaft being intermittingly rotated bya gear which engages with and cor- 8o responds to the gear 0 011 the shaft 0, the wires 3 3 being held and advanced between such feed-pulleys in the usual way. The barb wire H is intermittingly advanced in substantially the mode above described by means of the barb-feed pulley H seated on the shaft H journaled lengthwise of the machine and in termittingly rotated in the usual way by means of a pitinau, H, attached at one end to a crankwrist, D, on the outerend of the shaft D, and at the other end to a loose collar, H on the outer end of the shaft H, the collar H carrying a pawl, II, which intermittingly engages a ratchet, H fixed on the shaft H A short shaft (not shown) carrying a gear and feed 5 pulley corresponding to the pulley H and gear H is placed over the shaft-H, so that the barb-wire H is held between and interinittingly advanced by the pulley H and its twin pulley,in the usual and well-known mode.

' barb and strands.

The shaft D is rotated by means of a bevelgear, D, on its inner end, which is engaged and rotated by the contiguous bevel-gear B, on the driving-shaft B.

E E are twin guides through small holes 11, in the inner ends of which the wires y y, respectively, pass. The guides E E are long bars placed lengthwise of the machine, and are pivoted near their centers to a transverse horizontal stud, E, fixed on thefraine A. The outer ends of the guides E E extend, respectively, above and below the shaft B, andjp e given vertical oscillation in opposite directions by partially annular cams E formed on opposite sides of the shaft B, which flanges respectively act in the rotation of the shaft B upon friction-rollers E on the outer ends of the guides E, causing the, inner ends ofsuch guides to pass each other in a vertical are at each rotation of the shaft B, and the wires yy to cross each other vertically. The rollers E are held to the cams E by coiled springs E.

F is a shaft driven forward by the cam D, located on the shaft D, and confined in way F, formed in the plate J and cap F attached to the bed A, and is provided at its inner end with the horizontal cross-head F, which latter is further provided with -an inclined recess, F, and wedge-like horizontal stud F As the shaft F makes it's instroke, it forces the stud F between the strands y y and holds the latter apart and steady for the passage of the wire H and the end of the coiler between them, and at the same time places the recess F in position to receive the inner end of the barb H, and slightly raises the latter to position to be caught in the end of the coiler G. After the latter has coiled the barb between the wires y y, the shaft F has instantlyits outstroke and withdraws the stud F so as to permit the subsequent twisting of the strands y and be out of the way'of the onward movement of the The recoil or outstroke of the shaft F is caused by the coiled spring F attached at one end to the bed A and at the other to the cross-head F.

Referring to Fig. 4, which exhibits the mechanism for actuating the coiler G, J is a vertical plate seated on the bed A, transversely of the machine. In the inner end of the plate J- is journaled vertically a short shaft, G, to the lower end of which is rigidly attached the coiler G, the. latter being shaped like a corkscrew, and having its lower end slightly concaved to receive the barb H. The upper end of the shaft G is provided with a pinion, G which is rotated by a traveling rack, G carried in horizontal ways G formed in theupper end of the plate J. The rack G is reciprocated in said ways by means of a bell-crank lever, K, pivoted at its angle K to the bed A. The outer end of the lever K is provided laterally with a friction-roller, K, which traverses the elongated eccentric groove K in the cam K, fixed on the shaft D. The upper end of the lever K is attached to a pitman, L, and the latter attached to the rack by means of fastened to the back of the rack G and extending through a slot, J, in the plate J, parallel with the ways G, which slot J is traversed by the pin G Thus the coiler G is given the necessary rotation. It is necessary to intermittingly raise the coiler G to permit the point 00 of the barb H to cross its central portion. This is accomplished by allowing to a pin, G,

journal-bearing G, and pivotally attaching .the upper end of the shaft G at G to the inner end of the lever M. The. latter is pivoted near its center at M to the side of the and the outer end of such lever M rests upon and is actuated by a cam, M, on the shaft D, as shown in dot-ted lines in Fig. 4, being held to such cam by a coiled spring, M or the outer end of the lever M may be provided laterally with a friction-roller adapted to traverse a slotted cam on the shaft D, as does the roller K.

movable shear, forced over the shear N in the ordinary way by a cam-connection with the shaft B, to sever the barb H after it is seated from the barb-wire H.

The strands y y and barb-wire H are advanced in the usual way. The shaft F is driven inward, and the stud F forced between the strands y. y, and the wire H fed forward and its inner end slightly deflected upward in the recess F, and the guides E E simultaneously cross the strands y 3 close to the wire Hat the side of the latter next to such guides. The

coiler G is then depressed and given one rotation by the mechanism before described. The end of the coiler G engages the protruding end of the wire H and bends the latter between the strands y y and once around the point of crossing of said strands, as shown in Fig. 3. The coiler G is then instantly uncoiled and slightly raised, the shears N and O sever the barb, the shear 0 immediately withdraws, and the operation is complete, and the mechanism in place for a repetition.

R and S are the usual pawl and ratchet for regulating the feed of the strands y y.

I have had the machine in operation for several weeks, and it seats an average of one hundred and fifty barbs per minute, and can be driven to seat two hundred per minute.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

i 1. The combination of the coiler G, means for elevating and depressing such coiler, and meansfor causing the point of such coiler to perform a complete circle around the point of intersection of the strands yy, substantially as shown and described, and for the purpose named.
